Yesterday my discovery 2 (2003 with 108k miles) started having some overheating issues. It started overheating after sitting at long stop lights when I wasn't moving. Going anywhere in the 10-15 mph range would solve the issue. Drove it on the highway that night for 1-2 hours. Today it overheats while driving. I thought it was a fan since that had seized up 2.5 years ago and I replaced it with a smaller generic fan. Tested the fan and it works great, no issues. So before I start throwing parts at it, I'm hoping someone with more experience would know where a good place to start would be.
